GRAIN-BINDER.

SPECIFIQATION forming part of Letters Patent No. 279,210, dated June 12,1883.

r Application filed December 15, 1882. (No model.)

To all whom it may concern: 7

- Be it known that we, GEORGE L. WILLniMs and J ACOB DUNSTEDTER,residents of Edwardsville, Illinois, have made a new and usefulImprovement in Grain-Binders, of which the following is a full, clear,and exact description, reference being had to the annexed shaft used inoperating the compressor-arm and deck.

The same letters denote the same parts in the different figures.

The present improvement is especially adapted to what is known as theAppleby Twine-l3inder. In the binder referred to the bundles while beingbound lie upon a table and against a compressor-arm, H, and a leaf, B,at the outer edge of the table. Above the bundle is the breast-plate C,for confining the grain and preventing it from being entangled with theband-securing mechanism. -To permit the bundle to be discharged from thetable the compressorarm H is withdrawn, the leaf B, which is hinged tothe table, is turned down, and the discharging-arms are'moved to eject,the bundle. Difficulty, however, in practice is experienced from. themachine choking. The bundles, especially when large and when the grainis heavy and long, are liable to be caught between the table beneath andthe breast-plate and other parts of the binder mechanism above, andsometimes the operation of the binder is entirely arrested by reason ofa bundle being wedged above the table, as described. To obviate thisdifficulty is our present aim. I11 place of making the table a fixture,and simply withdrawing the compressor-arm and turning down the leaf atthe outer edge of the table, the outer portion,

A, of the table or deck, (as this part is variously called,) is mademovable, aswell as the compressor-arm and leaf, andwhile the bundle isbeing bound the table is upheld; but when it is desired to discharge thebundle the table itself is dropped, as well as the leaf and thecompressor arm, thereby providing more clearance for the bundle, whichcan now be readily delivered from the machine.

In the drawings, A represents the table; A, the lower or outer movableportion of the table; H, the compressor-arm; B, the leaf, which ishinged to the outer edge, a, of the table A C, the breast-plate abovethe table, and D the cam for operating the movable table, the leaf, andthe compressor-arm H.

E represents a shaft, which extends beneath the table and is used inconnection with the cam D to operate thecompressor-arm, the ta ble, andleaf, the cam moving the lever d, which is connected by means of thespring-rod d with a crank,' e, on the shaft E. A red, f, leads from thecrank f on the shaft E to the arm I) on the leaf B, so that when the camD depresses the lever d the leaf B is turned down upon its hinges Zr 1),and when the lever d is raised by said cam the spring-rod (7 acts toturn the leaf up again.

The compressor-arm H is pivoted at 71 and by means of the link It isjointed to the crank f, and in consequence of the rotary reciprocatingmovement of the shaft E the compressorarm H is raised above and droppedbeneath the table A, as shown in the two positions of the arm in Figs. 1and 2, respectively.

The shaft E is made to serve an additional purpose. The movable portionA of the table is made so that it can be dropped downward away from thebreast-plate and binder mechanism located above it. To this end thetable A may be hinged to the part A, or to any other suitable fixedpart, so that it can be depressed when desired below the level of thepart A; but the preferable mode of carrying out this part of theimprovement is that shown, 7

and catching between it and thelowertable, A.

XVe claim 1. An Appleby grain-binder having that portion of the deckwhich supports the bundle while being bound movable toward and from thebreastpl ate or other upper confiningsurface, and also having thecompressor-arm adapted to be raised above and dropped below said deck, for the purpose described.

2. The combination of the movable deck A, the leaf B, the shaft E,having cams e e, and connecting mechanism for operating said leaf,substantially as described.

3. In a self binding harvester, the compressor-arm, in combination withthe bindingtable adapted to be depressed by the pressure and weight ofthe bundle, means for raising said table and supporting it while thebundle is being formed and bound, and mechanism connected to saidraising means, whereby when the latter is operated to permit the tableto fall the compressor-arm will be depressed below the table,substantially as described.
